How to Combine Duplicate Rows and Sum the Values in Excel: A Step-by-Step Guide

Combining duplicate rows and summing the values in Excel can seem like a daunting task, but it’s actually pretty straightforward once you know the steps. In a nutshell, you’ll use Excel’s built-in features to clean up your data. By the end of this process, you’ll have a streamlined dataset where duplicates are removed and their corresponding values are summed up. Ready to dive in? Let’s get started.

How to Combine Duplicate Rows and Sum the Values in Excel

In the following steps, we’re going to walk you through how to find and merge duplicate rows in Excel, while summing their values. This will help you keep your data organized and efficient.

Step 1: Select Your Data

Highlight the range of cells that you want to work with.

Make sure to include all columns that contain data you want to combine. If your dataset is large, you can press Ctrl+A to select everything.

Step 2: Open the "Remove Duplicates" Tool

Navigate to the "Data" tab on the toolbar and click on "Remove Duplicates."

A dialog box will appear, showing all the columns in your selected range. This is where you choose which columns to check for duplicates.

Step 3: Choose Columns

In the "Remove Duplicates" dialog, select the columns you want to check for duplicates, then click "OK."

Usually, you’d select columns that uniquely identify each row. For example, if you’re working with sales data, you might select columns like "Product ID" or "Customer Name."

Step 4: Remove Duplicates

Click "Remove Duplicates" and then "OK" in the dialog box.

Excel will notify you of how many duplicates were removed. This step ensures that all duplicates are taken out, but it won’t yet sum the values.

Step 5: Use Pivot Table

Go to the "Insert" tab and choose "Pivot Table."

A new window will pop up, asking you to confirm the range of your data and where you want the Pivot Table to appear.

Step 6: Set Up Pivot Table

Drag the column header you want to combine duplicates for into the "Rows" area, and the column with values you want to sum into the "Values" area.

This will create a Pivot Table that sums the values for each unique item, effectively combining duplicates.

Step 7: Copy and Paste

Copy the resulting Pivot Table and paste it back into your original worksheet if needed.

This will replace your old data with the cleaned-up version, now free of duplicates and with summed values.

Once you’ve finished these steps, your data will be clean, with duplicate rows merged and values summed. This organized dataset will be much easier to work with.

Tips for How to Combine Duplicate Rows and Sum the Values in Excel

  • Back Up Your Data: Always make a copy of your original data before making any changes.
  • Check for Errors: After removing duplicates and summing values, double-check your results for any mistakes.
  • Use Filters: Utilize Excel’s filtering options to better navigate large datasets.
  • Learn Shortcuts: Keyboard shortcuts like Ctrl+A (select all) and Ctrl+C (copy) can speed up your work.
  • Stay Organized: Keep your data well-organized in columns with clear headers to make the process smoother.
